Steering improvement?
If your MB feels light on the front end and does not have good directional stability or self-centering, it is probably in need of alignment. I am told that the GLK needs special alignment tooling not normally found outside the dealership. I do not know if this is true or not, but the vehicle needs alignment.

3.5L, we used to call them suicide knobs. Haven't seen one in ages.
Seems we could leave figure 8 tire tracks with the knob. No problem-O
